A wringer mop apparatus in accordance with manually actuated thisinvention includes bined holder and. wringer mechanism I6 for a mop I5of the endless type, a carrier I I for mechanism I6, a handle I8 for thecarrier I1, and a operating means I9 for the mechanism I6. There isshown a form of a combined mop guiding and carrier supporting element 20which may be used in connection with a water container when wringing themop as illustrated in Figures 2 and 3.

The spring controlled combined mop holding and wringing mechanism I6 hasthe mop I5 permanently connected thereto. When a mopping action iscarried out the mop I5 is arranged in outwardly extended relation withrespect to the mechanism I6. The latter includes a revoluble outerwringer or holder roller 28. The mounting fixed shaft 33 extends throughbore 3| and is of greater length than the length of roll 28. Theperiphery of the latter is smooth throughout. The roll 29 is formed witha pair of oppositely disposed axial sockets 34, 35 opening at theopposite ends thereof. The socket 34 is of polygonal cross section. Thesocket 35 is of cylindrical cross section. The periphery of the roll 29is formed throughout with spaced cavities 36. The roll 29 is capped ateach end as at 37.

to the rolls for the purpose of disposing mop I5 in outwardly extendedrelation with respect to the mechanism I6. The clamping function of roll29 is transmitted from the structure 30. The cavities 36 function to aspring controlled comy 1 for applying pressure assist in the clamping ofthe mop to mechanism l6, due to the fact that spaced portions of thebody part of the mop will be forced into several of the cavities whenthe mop is clamped to mechanism l6. When the mop is to be subjected to awringing action, the pressure on roll 29 is relieved to the desiredextent to permit of a stretch of the body part of the mop beingsuccessively compressed for expelling the water to the desired extentand for said stretch to be moved inwardly or outwardly with respect tothe rolls.

The compression structure 36 of the mechanism I6 includes a pair ofvertically adjustable spaced parallel slides 4|, 42 which are slidablyarranged on the outer faces of the lower portions 43, 44 respectively ofthe sides 45, 46 respectively of the carrier l1. The lower portions ofthe sides of the carrier H are slotted as at 41 and such slots extendfrom a point removed from the lower ends of said lower portions to abovethe upper ends of the latter. The slides 4|, 42 extend across the slots41 in the side portions 43, 44, as well as extending slightly below thebottom of said slots. The slide 4| is formed with an opening 48 and anopening 48 below and aligning with the opening 48. Integral with theinner face of slide 4| and registering with the openings 48,49 areinwardly extending flanged bearings 48 49 respectively which passthrough the slot 41 of and slidably connect the slide 4| to carrier side45. The ends of the roll 29 and the caps 31 on such ends arecountersunk. The countersink at one end of roll 29 has mounted thereinthe bearing 49 Positioned against the outer face of the slide 4|, aswell as being suitably secured to slide 4| for the purpose of bodilymoving with the latter is a casing 56 having arranged in the upperportion thereof a gear wheel 5| which meshes with and drives a gear 52arranged in the lower portion of the casing. The gear wheel 5| has a hub53 which extends outwardly and inwardly with respect to casing 56. Thegear wheel 52 is provided with a hub 54 which extends outwardly andinwardly with respect to casing 56. A flange bearing 55 is provided onthe inner end of hub 53 and which abuts the inner end of bearing 48 Theinner part of hub 53 extends through the bearing 48 The hub 53 isfixedly secured to a polygonalshaped driven shaft 56 for operating gear5|. The shaft 56 extends inwardly from slide 4|. The hub 54 of gearwheel 52 is fixedly secured to the shaft 38. Flanged bearings 56 areused for the outer portions of the hubs 53, 54. h

The structure 36 includes a resilient pressure applying or spring member51 of skeleton form provided with reduced ends 58, 59. A means toprevent the spreading of thereduced end 58 is indicated at 66 and ameans to prevent the spreading of the reduced end 59 is indicated at 6|.The reduced ends 58, 59 of the member 51 extend through the upper endsof the slots in the lower portions 43, 44 of the sides 45, 46 of thecarrier H. The reduced ends 58, 59 of the member 51 bear respectively onthe upper ends of the slides 4|, 42, thereto whereby the slides will beshifted to an extent to provide for roll 29 clamping the body part ofmop |5 against roll 28.

The structure 36 includes a compression controlling means for member 51consisting of an upstanding rod 62 having a threaded lower portion 63.The rod 52 extends through the member 51 and carries a sleeve-likeadjustable nut 64 which engages with the threads 63 and is employed forincreasing and decreasing the tension of member 51. The nut 64extendsthrough the member 51 and is formed in proximity to its lower end withan annular peripheral groove 65 in which is seated member 51 whereby thelatter is connected to rod 62 above the lower end of the nut. Theadjusting of the nut 64 towards the lower end of rod 62 increases thetension of member 51 and an increase of pressure against the upper endsof slides 4|, 42 which in turn will transmit such pressure to roll 29 totightly clar'np mop |5 to mechanism l6. The upper end of the rod 62 isoffset as at 66 to provide a clearance for a transmission shaft, to bereferred to, of the operating means for the mechanism l6. The offsetportion 66 of the rod 62 has its upper part 61 extended into the handlel8 and also into the body of the latter as at 68. The part 61 isanchored to handle |8 as at 66. The member 51 is of arcuate contour. Theslide 42 is formed with an opening 16 and extending through and integralwith the wall of opening 16 is a flanged bearing 1| which passes throughthe slot 41 in side portion 44 and slidably connects slide 42 to carrierside 46, The shaft 39 revolves in bearing 1| and is bodily carriedtherewith when the slide 42 shifts in opposite directions simultaneouslywhen the slide 4| is shifted in like directions. The bearing 1| extendsinto the countersink at the other end of roll 29.

The lower portion 43 of the side 45 of the carrier H is formed with akey-hole shaped opening 12 for receiving the reduced portion 13 of theshaft 33 for the purpose of removably connecting the end 13 of shaft 33to one side of the carrier H. The lower side portion 44 of carrier H hasan opening 14 and an inwardly extending tubular bearing 15 registeringwith the opening 14. The shaft 33 extends through bearing 15 and thelower side portion 44. The shaft 33 at its other end is enlarged as at16 to provide a head abutting the outer face of portion 44 of thecarrier H. The head 16, in connection with the reduced portion 13 andopening 12 act to detachably connect shaft 33 to the carrier IT. Thebearing extends into axial bore 3| of roll 28. The cap at the other endof roll 28 is formed with an inwardly extending tubular bearing 18 whichregisters with the axial opening thereof and extends into the axial bore3| of roll 28. The bearing 18 is arranged in endwise alignment with thebearing 15. The shaft 33 extends through the bearings 15, 18. The roll28 revolves about shaft 33 and bearing 18. The shaft 33 furtherfunctions as a means for connecting the side portions 43, 44 of thecarrier together to prevent the spreading of such portions.

The carrier H has its sides 45, 46 of like form, but oppositely disposedand said sides not only include the outer portions 43, 44 but also innerportions 19, 86 as well as intermediate portions 8|, 82 extendingtowards each other at an inclination from their lower to their upperends whereby the upper portions 19, 86 will be inset with respect to thelower portions 43, 44. The upper portions 19, 86 are secured againstopposite sides of the lower end of handle |8 by the holdfast means 83.The lower ends of the lower portions 43, 44 are provided with inwardlyextending flanges 84. The portions 43, 44, 8|, 82 in cross section areof inwardly opening channel-shaped contour. The portions 19, 86 in crosssection are of segmental contour.

The handle l8 includes a solid section 85 and a tubular section 86. Thelower end terminal portion 81 of section 85 is reduced and extends intoand frictionally engages with the inner face of the outer end of section86. The latter in proximity to section 85 is formed with a pair ofdiametrically opposed openings 88, 89. The opening 88 is of greaterdiameter than the opening 89. Encompassing and secured to the section 86is an annulus 90 which is enlarged at one side as at 9|. The annulus 99is formed with a pair of diametrically opposed openings 92, 93. Theopening 92 is of greater diameter than the opening 93 but of lessdiameter than the opening 88. The opening 92 registers with the opening88. The opening 93 is of the same diameter as the opening 99 andregisters therewith.

The manually actuatable operating means I9 for the mechanism I6 isemployed for revolving the roll 29 which in turn will provide for therevolving of the roll 29. The means I9 includes an operating shaft 94disposed lengthwise of the section 86 of the handle I8. Within thesection 86 is arranged an inverted cup-shaped upper bearing 95 for andhaving an axial opening 96 through which passes shaft 94. Arrangedwithin the section 89 is an inverted lower cup-shaped bearing 91 for andhaving an axial opening through which passes shaft 94. The latterextends upwardly from bearing 95 and has fixed to its upper end abeveled pinion 99 meshing with a beveled gear I fixed to the reducedportion of a shaft I02 disposed in transverse relation with respect tosection 86, mounted in one end in the openings 89, 93 revolublyconnected at such end to annulus 90 and having its other end I03 reducedand peripherally threaded. The gear I00 has a part thereof arranged inopening 98. The hub of gear I00 is mounted in and extends outwardly fromopening 9!. The outer end of the hub of gear I 00 is reduced. Positionedon the reduced portion of the hub of gear I00 and bearing against theremaining portion of the hub is a crank I04 provided with a handle meansI05. The crank I04 is clamped on the hub of the gear I00 by a clampingnut I06 secured to the end portion I03 of shaft I02. On the revolving ofthe crank I04 shaft I02 will be carried therewith, as well as the gearI00 whereby the latter meshing with the pinion 99 will provide for theoperation of shaft 94. The bearing 91 is cut away as at I0'I (Figure 6)to provide a clearance for the part 61 of the offset upper portion 66 ofthe rod 62. The lower end of shaft 94 has fixed thereto a stop collarI08 which coacts with the lower bearing 9'! to arrest the upper shift ofshaft 94. The downward shift of shaft 94 is arrested by the hub ofpinion 99 engaging with the top of the upper bearing 95.

The operating means I9 includes a transmission shaft I09 formed of apair of telescopic sections H0, III and with the section I I0 slidablyarranged in and extended from the lower end of section II I. The shaftI09 is disposed at an to the inner end of the shaft 56. The section IIIof the shaft I09 is universally connected at its upper end with thelower end of the shaft 94 as indicated at H3. When the combined guidingand supporting element 20 is employed it is mounted upon spaced portionsof the top edge I I4 of bucket II during the wringing operation and itnot only functions to guide stretches of the mop I 5 but further acts asa support for the carrier I'I.

When the shaft 94 is operated, on the revolving of the crank I04, thetransmission shaft I09 will be revolved from shaft 94, and shaft I 09will transmit a revolving movement to the shaft 56 which in turn willrevolve the gear 5|, provide for the operation of gear 52 and therevolving of roll 29 and which in turn will provide for the revolving ofthe roll 29. The operation of the rolls 28, 29 is had when the to theshaft 56 the roll 29 may be operated in a clockwise or an anticlockwisedirection.

By pressing upwardly the roll 28 at a point in proximity to carrier sideportion 43 shaft 33 may be disconnected from the carrier and carry roll28 therewith for the purpose of removing or connecting the mop from andto said roll.

Although the mop is shown as embodying a pair of ties for the mop body,yet it is to be understood that the number of ties may be increased asdesired.

In operating the tion is then applied to the mop and the latter will becaused to assume the position shown in Figure 2, that is, exteriorly ofthe bucket or pail.
